COMBINED CHURN AND BUTTER-WORKER.

SPECIFICATION forming part 0f Letters Patent NO. 619,291, dated VEebruary 14, 1899.

Application filed March 7l 1898. Serial No. 672,808. (No model.)

To @ZZ whom it may concern,.-

Beit known that I, HENRY L. FERRIS, acitizen of the United States of America, residing at Harvard, in the county of McHenry and State of Illinois, have invented certain new and useful Improvements in a Combined Churn and Butter-Worker, of which the following is a specification.

My invention relates to certain improvements in combined churns and butter-workers; and it consists in certain features of novelty designed to render the same more rapid, efficient, and easy to operate and keep clean.

The invention is illustrated by means of three sheets of drawings containing six iigures, of which- Figure lis a vertical diametrical longitudinal section of the machine. Fig. 2 is a vertical cross-section in line 2 2 of Fig. 1, looking toward the drum or barrel. Fig. 3 is a similar section in line 3 3 of Fig. l, looking in the same direction. Fig. 4 is a section in line 4 4 of Fig. 5, looking from left to right. Fig. 5 is a section at right angles to Fig. 4 in line 5 5 of the latter figure, and Fig. 6 is a partial view similar to Fig. l of a modified construction.

Referring first to Fig. 1, A A are two brackets suitably supported and having j ournaled in their tops two gudgeons b b', secured to the opposite ends of a churn-barrel B, here shown as fastened to the gudgeons by means of bolts b2. This barrel is provided upon its inside with a series of longitudinally-arranged inwardly-extending wings or ribs b3, the function of which is to agitate the cream in the churning operation and to cooperate with other devices to work the butter after it is churned. These ribs do not extend entirely to the barrel-heads, but are fitted at their ends to rings C C', substantially triangular in cross-section and themselves fitted into the corners of the barrel to prevent the butter from collecting in said corners and also to make the same easy to clean and keep in proper condition. In the inner surfaces of the gudgeons b b are sockets b4 b5, in which is journaled a shaft D, having two links d d', secured upon it against rotation and preferably, though not necessarily, free to swing together and with the shaft. In these twol links is journaled a second shaft D', upon the opposite ends of which are hung two weighted arms E E', preferably secured against rotation upon the shaft D', and carrying at their free ends a third shaft F, also preferably secured against rotation in the sectors and -which has journaled upon it a corrugated roller G.

The barrel is rotated by means of a drivingpulley H, mounted upon a shaft h, journaled in the bracket A and carrying a pinion I, which meshes with an internal gear or annular rack J, secured to the adjacent head of the barrel.

The weight of the arms E E is relied upon to keep the roller G in or near the bottom of the barrel and to return it thereto when forced out of such position by an accumulation of butter.

1f, as in the preferable construction, the links d d are secured against independent rotation or oscillation with respect to each other and the arms E E are similarly secured with respect to each other, the axis of the roller G will be kept at all times parallel to that of the barrel, and yet the roller will be perfectly free to oscillate upon either of the two axes marked by the centers of the shafts D D. The weight of the arms E E tends to keep the links d cl in a vertical position, so

lthat if the roller is carried around by the butter until it rises materially from the bottom of the tub such movement Will gradually withdraw it from the inner surface of the barrel, tending to allow the butter to pass through, and, furthermore, the crowding action of the butter will tend to force the links d d out of a vertical position toward the opposite side of the barrel from that occupied by the roller and carry said roller still farther from the walls of the barrel, thereby also aiding in the passage of the butter between the two.

In the operation of the machine as a churn the roller hangs downward, as seen in Figs. l and 3, and acts as a sort of stationary dasher to agitato the cream as the latter is thrown against it by the rotation of the barrel. As soon as the butter is churned the roller immediately commences to work the same between it andthe internal wings or ribs upon the barrel.

The advantages of my device I consider to be its great simplicity both in construction and in operation, together with the ease with which it may be taken care of and the eiliupon said bearings, connecting devices beciency with which it does its work.

The modilication shown in Fig. 6 varies from the construction shown in the other figures merely in the substitution of a short pin X for the shaft D' at each end of the machine to pivot the arms E E upon the links d d. In this case the arms E E are secured against independent oscillation by means of the shaft F, to which said arms are preferably keyed.

I claim as new and desire to secure by/Letters Patents 1. In a combined churn and butter-worker the combination with a rotatable barrel, of a freely-oscillatin g weighted roller hung within the barrel adjacent to the inner surface thereof and upon an axis of oscillation eccentric to the aXi-s of the barrel; substantially as described. j

2. The combination in a combined churn and butter-worker of a rotating' barrel, a shaft journaled in the barrel concentric with the axis thereof, a'pair of links hung upon the shaft adjacent to the opposite ends of the barrel, a pair of weighted arms pivoted respectively to the respective links and a roller j ournaled between the free ends of the weighted arms and adjacent to the inner surface of the barrel substantially as described.

3. The combination in a combined churn and butter-worker and with arotating barrel, of ashaft journaled within the barrel concentric with the axis thereof, a pair of links secured against rotation upon the shaft adjacent to the opposite ends of the barrel, a pair of weighted arms pivoted to the free ends of the links and themselves secured against independent oscillation with respect to each other and a roller journaled between the free ends of the arms and near the inner surface of the barrel; substantially as described.

4E. In an apparatus of the class described,the combination with a suitably-mounted rotating barrel, of bearings within and at opposite ends of the same, freely-oscillating links hung tween said links preventing angular movement of one with respect to the other and a roller j ournaled between the free ends of said links; substantially as described.

5. In an apparatus of the class described,the combination with a rotatably-mounted barrel, of bearings within and at opposite ends of the same, a pair of-freely-oscillating links pivotedat one end to said bearings, a second pair of freely-oscillatinglinks pivoted at one end to thefree ends of the first pair and a roller journaled between the free ends of the second pair; substantially as described.

6. In an apparatus of the class described,the combination with a rotating barrel, of bearings within and at opposite ends thereof, a pair of freely-oscillating links pivoted at one end to said bearings, connecting devices holding each of the links against angular movement, independent of the other, a second pair of freely-oscillating links pivoted at one end to the free ends of the iirst pair, connecting devices between the second pair of links preventing independent angular movements of one with respect to the otherand a roller journaled between the free ends of the second pair of links; substantially as described.

In witness whereof Ihave hereunto set my hand, at Chicago,'in the county of Cook and State of Illinois, this 25th day of February, A. D. 1898.
